Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain. They have a silicone O-ring above the threads for a tight seal. Install them at the lowest point of the enclosure. Breather vents meet IP66 for protection in washdown environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.

Brass breather vents have good corrosion resistance.

Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures. All have a hydrophobic and oleophobic filter membrane that blocks moisture and contamination from particle buildup.

Nickel-plated brass vents stand up to corrosive environments better than nylon and polycarbonate vents. They’re also durable, which means you won’t have to replace them as often.

These valves are often used to remove air pockets in cooling and heating systems to maintain consistent flow and prevent water surges that can damage equipment. All have a vented relief port to exhaust discharge directly.

Valves with female/male inlets have an inlet with both male and female threads, so they can be connected to both male and female adapters and equipment ports.
